<p>A system and method are provided for spectral imaging an object or scene 2. A first image 2a of the object or scene 2 is projected on a spatial modulator 6 and divided into a plurality of first image segments 2a' modulated with a respective plurality of modulation frequencies f1-fN. A spectrally resolved second image segment 2b' of each first image segment 2a' is projected onto a sensor 4 forming a second image 2b in such a way that overlapping spectral components » of different second image segments 2b' on the sensor 4 originating from different first image segments 2a' have distinct modulation frequencies f1-fN. The projected second image segments 2b' are read out from the sensor 4 and demodulated according to the distinct modulation frequencies f1-fN. In this way projected second image segments 2b' overlapping on the sensor 4 may be distinguished on the basis of the distinct modulation frequencies f1-fN.</p> |
